The aim of this study must increase our understanding of heat and mass transfer in non-Newtonian Sutterby fluids, which are widely used in industries like polymer production. Especially when examined through the perspective of the Cattaneo–Christov heat flow theory, it greatly enhances diffusivity and thermal conductivity and introduces new theoretical possibilities by accounting for dynamic fluid characteristics. The impact of heat generation and absorption, mixed convection, and nonlinear thermal radiation along a stretching cylinder are all thoroughly examined in this work, which makes it significant. The convective boundary conditions are considered in this study. The formulated system of partial differential equations (PDEs) is converted into system of ordinary differential equations (ODEs) by employing appropriate similarity transformation. This adopted set of ordinary differential equation is tackled computationally utilizing the RK-Fehlberg 4th-order approach based on shooting technique. The impression of significant physical variable on thermal, velocity, heat transport, concentration, streamline, and mass transport are discussed graphically. The findings indicate that the velocity curve diminishes as the Sutterby fluid parameter increases. The thermal profile is enhanced by increasing the temperature ratio parameter and Biot number. Higher levels of the Lewis number are associated with a reversal tendency observed in the concentration profile and local Sherwood number. [ABSTRACT FROM AUTHOR]

Peristalsis of nanofluid is significant in cancer treatment, ulcer treatment and industrial equipment. This study simulated the MHD peristaltic transport of Sutterby nanofluid with mixed convection and Hall current. Partial slip and convective conditions are imposed for flexible channel walls. Energy and concentration equations are modeled by considering the effects of Joule heating, thermal radiation, viscous dissipation and activation energy. Buongiorno nanofluid model is employed which features thermophoresis and Brownian movement aspects. The resulting nonlinear system of equations is numerically solved after employing the large wavelength and small Reynolds number supposition. Graphical analysis for the velocity, temperature, concentration, heat transfer coefficient and entropy generation is analyzed. It is observed that velocity has opposite behavior for mixed convection parameters. Temperature and heat transfer rate enhanced for Brownian movement and thermophoresis parameters. Concentration rises against larger activation energy and radiation variables. Further entropy declines against higher diffusion parameter. [ABSTRACT FROM AUTHOR]

A theoretical study is conducted for magnetohydrodynamic pumping of electroosmotic non-Newtonian physiological nanoliquids through a two-dimensional microfluidic channel. The Sutterby rheological nanofluid model is utilized to characterize the liquid. The normalized two-dimensional conservation equations for mass, longitudinal and transverse momentum, energy and solutal concentration are reduced with lubrication approximations (long wavelength and low Reynolds number assumptions). A coordinate transformation is employed to map the unsteady problem from the wave laboratory frame to a steady problem in the wave frame. Slip and convective conditions are imposed at the channel walls. The emerging boundary value problem is solved numerically using MATLAB software. The flow is effectively controlled by many geometric parameters, viz., electroosmosis, Hartmann and Sutterby fluid parameters. It is observed from the analysis that the rise in magnetic and electroosmosis effects leads to a reduction in the axial velocity field. The radiation parameter decreases the temperature for the positive value of Joule heating parameter and the trend is revered for the negative Joule heating parameter. This study is encouraged by exploring the nanofluid dynamics in peristaltic transport as symbolized by heat transport in biological flows, novel pharmacodynamics pumps and gastrointestinal motility enhancement. The study is also relevant to MHD biomimetic blood pumps. [ABSTRACT FROM AUTHOR]
